' Application filed February 11i,v 1920. SerialV No. 357,886.

To all whom t may concern Be it known that I, F RED P. ANGELL, a citi- Zen'of the United States, residing at Battle Creek, in the county of Calhoun and State of Michigan, have invented certain new and useful Improvements in Dual Valves for Hyd'rants, of whichthe following description, taken in connection with the appended claims and accompanying drawings, forms the specification.

The present invention relates-to that class of valves operating against/Huid pressure, and in which a primary valve' operates in conjunction with a check valve for the pur- A characteristic feature `and important object of the present invention is a means for insuring the seating of valves regardless of [fluid pressure passing through the saine.

The significance Ais of importance where several hydrants lead from a common pipe line andespeciallywhere thehydrants are located one above the other',` vas in buildings of several stories. l"A hydrant using near or full capacity of a'pipe antecedentV to other hydrantson the same'line causes a 'les'sening of'pressure'on vsuch hydrants, and "unless some vautomaticmeans is provided to keep the `valves closed `under such circumstances, leakage, and'waste of water will result when pipes are 'not at capacity pres- Other objects and featuresof the invention are:` to so construct both the primary and check lvalves as to insure perfect seating; to vobvi'ate the necessity of a packed joint about the operating spindle; and to so construct the vnoa'zle that the same mayv be used fory a drinking fount. These and other objects and advantages will hereinafter appearto those familiar`-with and skilled in the art to which this invention appertains.v -In thedravvings forming a part of this specification, Figure l is a side sectional. elevation of my improved dual-valve closed, the

l have shown the invention as constructed for use on sinks and the like where vertical same is not necessarily limited to lsuch usages, as it would be evident-that a horizontal construction Wouldwork to equal 'ML vantaga .hydrants arevcommonlyf used, although the Like marks of reference refer to corre` 'sponding or equivalent parts in the differ entviews, in which A represents a sink' or other frame or top through which the shank or main barrel `l of the faucet is anchored.

As shown, the lower end of this barrel is eXteriorly L screw-threaded and receives the interiorly screw-threaded upper endof an exteriorly threaded union 2; This union at its lower end is reduced and is also screwthreaded (either interiorly or eXteriorly) to receive a conducting pipe, the union near its lower end forming an internal' annular shoulder' 3 for the seating'ofa coil spring 4, the'object ofwhich will be morefully described: hereinafter. i V

The upper end of the barrel l' is burred 1 outwardly and forms ariin 5 against which an interiorly screw-threaded collar 6 is tit- 'ted and vinto'which a neck ofthe hydrant head B is'screw-threaded.

As shown, the upper clamping or rseating collar 7 is screw-threadedon to the upper ,end ofthe barrel l, and-immediately below the burred rim of said barrel, I vhich,v to- 'gether with a secondary collar 8,- screwv threaded over the union 2, clampsjthe hy- "drant'to a sink or other fixture, as A The head B is formed with a transversely *arranged housing and is slightly offset onthe side ofthe barrel 1 opposite to 'the` nozZle 9, and within this housing the operating Vspindle 10 is j ournalled. This housing at oneend is closed and bored out and forms 'a bearingv I for theinn'er end of thespindle 10,'thefopposite end of thevv spindle passingthrough a packing nut 11' 'screw-'threaded into vthe open free' *outer end lbeing squared v andi fitted with passing throughthe ,nut `11 is'tapered vand forms `a cone 13bearing intoxa correspondingly formed opening.or seat 14 in thek nut 11, and its opposite bored-out or chan'lbered endis provided with a coil spring seating against the closed head of the offset housing and keeps the cone bearing 13water tightl in the nut 11. l n

An arm 16 extends from-the spindle-10 and overhangs the barrel 1 for the purpose of operating the valve mechanism within the same.v This mechanism comprises a guide Y tofreely pass` through the hydrant when the valves are opened; the lower end of the same is turned and forms the cone valve V18 seating within a` correspondinglyformed valve seat at the lower end of the barrel 1.

The lower end 21 of the guide 17 is extended below the valve 18 and slotted to receive a screw driverfor the purpose'of renewing or grinding the surfaces between the valve and its seat by the use of oil and emei'y orother abrasive material. p

The spring 4 within the union 2 at its upper end bears. against the valve 18 and ini' mechanism,

sures the seating of the valve 18 and the primary .valve 19, either with or without fluid-,pressure in the hydrantiand also prevents the kclattering of one or bothl valves, andthe wearing of their seats, a-feature often noted .in hydrant and other valve v The upper end yof the guide 17 isA chambered sufficiently deep to receive 'the' coil spring 20 between vthe bottoml ofthe chamber and the lower end of a stem 22 to which :the valve 19 is attached.- This valve is of rubber', leather or other suitable materialk vand flies between a shoulder formed at the upper'end of the stern 22 and aishoulder' of a screw 23 screw-threaded intorsaid stein,

the upper end ofthe screw forming a stem extending'. through an indrawn neck portion ,24 of the housing B, and formsa yvlave seat ffor-the-valve 19. @The stern is located at the extremity and belowthe' tip ofthe over- Y hanging arm 16 of theoperatingspindle 10.

, `To insurefa perfect fluid tight joint withi outthe.use-offibre or-other resilient material', or-soft'metalfpacking, theneck 25 of :the-housing B is bored lout'flaring andthe )rim i5of,--tliebarrel= lta-pered to fit within the sameso that When the'l collar xand-:the' neckl Ioff-the housing arescrewed together,

Y Y f The nozzle 9 is screw-threaded? where it joins with a reduced portion ofthe head B,

the samehaving a slot 26 forinedat its end,

and the nozzle is providedwith aV stud 27 which operates in the'slot for the purpos'e'ofV Y limiting the turning of the nozzle beyond a predetermined oint, the limiting-'points being such that t e nozzle maybe directed in an upward and a downward.position,the

former for the purpose of Vvusing Vthe same for a drinking fount, the latter as a faucet for general usages. The nozzle atits curved end is formed with a bulbular head V28Vand it may 'be'providedvwith a ,baille` plate, ball or yother obstruction' for .preventing a "direct forceful current of ,water fromfleavingthe same, a feature desirable. especially when used asia drinking fount. Hydrants ofsthe character are especially desirable andf useful in buildings of severalv stories'where waterV is takenfrom the saine pipe line, not alone V for the reason of being perfectly yselfsealing under `pressure or no pressure, but also. for` .the convenience of being readily'repaired above the sub-valve without cuttingv off 'the V water supply@ l f V- 1 VI am aware that hydrants have been made in which twoivalves are'eniployed operatingagainst liquid 'pressure. but I am `not. aware Y of a hydrant being usedninwhich the yvalves were operative independent of liquid pressure or self sealing. i Y, v

From the foregoingfivexplanation of thearrangement and construction of/thefvalves as used for avertical hydrant, taken in con-y nection with the accompanying'drawings, a

more extended explanation .of its workings and advantages is believed-to be lunnecessary.

Having', therefore, setV forththe objects and advantages of my improveddual valve for hydrants, what I claim-,asv new and desire to secure by Letters Pate/nais 1.A In a devicel of the class set forth,the
